2 Claims. (01. 157-426) This invention relates to tools for removingtires from wheels, and more particularly to a device of that characteradapted for removing the tires from tractor or truck'wheels.

Tires which have been on the rim of a wheel for some time will adhere tothe rim to such an extent that it is very difiicult to release the tirefrom the rim with ordinary tools now available. The rims of the wheelsare usually made from steel and there is a tendency for the flanges,

and adjacent metal to rust and thus form a bond between the tire beadand the rim.

The present invention is adaptable for removing tires from what iscommonly known as dropcenter rims on which pneumatic tires are used, oris adaptable for other tires, such as solid rubber tires, also having abead engaging the rim of the wheel. In using the device on pneumatictires, the rusting of the metal forms a bond which must be broken beforthe tire can be removed from the rim. Care should be exercised toprotect the tire and tube from injury.

The principal objects of the present invention are to provide a tool forengaging the tire at the juncture with the rim to which the tire isattached and on which downward force may be exerted to break the bondbetween the tire and rim; to provide a device for holding the tire withrelation to the tool for removing the tire from the rim so that the bondbetween the tire and rim may be broken; to provide a device which willhav direct leverage contact with the tire adjacent the rim for exertingforce on the tire to break the bond therebetween; to provide a devicewhich may be adjustable to fit tires of different size; to provide adevice adjustable for removing various size tires from rims andproviding the desired leverage for tires of greater size; and to providea simple, economical and efficient tool for this purpose which may beused for the purpose set forth.

In accomplishing these and other objects of the invention, I haveprovided improved structure, the preferred form of which is illustratedin the accompanying drawings, wherein:

Fig. 1 is a side View of a tool embodying my invention, showing a tirein cross-section with a tool engaging therewith, and a modified form ofthe leverage mechanism being shown in dotted lines.

Fig. 2 is a perspective view of the invention with the handle beingshown in disassembled relation.

Fig. 3 is a cross-sectinal plan view taken on a line 3-3, Fig. 2.

Referring more in detail to the drawings:

l designates a tool for removing tires embodying the features of myinvention, comprising a base plate 2, uprights 3 and 4 rigidly securedto the base plate by welding or other suitable means, and spaced apartto provide a channel 5 therebetween. A brace 6 is rigidly secured to therear of the base plate by welding or other suitable means, as indicatedat I, having its upper end secured at substantially the center of theuprights by brazing, welding or other suitable means.

The lever arm 8 is pivotally secured between the uprights 3 and 4 atsubstantially the upper end of the uprights by a pin 9 through suitablebore openings In in the arm and in the uprights, as indicated at H. Aplurality of openings [0 and II may be provided in the arm and uprightsso that the arm may be adjustable with respect to the standard to adaptthe device for different size tires, the larger tires requiring thelever arm to be raised to the upper openings in the uprights and forgreater leverage, the arm is lengthened by inserting the pin 9 throughthe rear opening in the lever arm. A handle 12 having a bore opening I3is provided to fit over the end M of the lever to provide greaterleverage to the arm 8.

Pivotally secured to the arm 8 by a bolt or the like l5 are links l6 andI! having their lower ends rounded, as at [8, and adapted to receive andbe pivotally secured to the lower ends by a bolt I9 is a bar 20 twisted,as indicated at 2|, to provide a flat lower end with the extreme outerpart bent slightly, as indicated at 22, to engage between the bead of atire and the rim, as indicated at 23, Fig. 1, when the device is inposition to be operated.

The uprights 3 and 4 are provided with a plurality of openings 24adapted to receive a bolt or the like 25 for pivotally mounting a hook26 on the outer side of the uprights 3 and The hook 2B is spaced fromthe uprights by a bushing 21. The inner end of the hook is provided withbore openings 28 for adjusting the length of the hook with respect tothe tire being removed.

In Fig. 1 is shown a tire 29 lying on the base 2 attached to a rim 30 ofa Wheel (not shown).

Operation of a device assembled and constructed as described is asfollows:

The tire to be removed from the rim is placed on the base plate 2 withits lower surface contacting the uprights, as indicated at 3|, Fig. 1.The end 22 of the bar 20 is placed so that it will contact the bead 32of the tire between the bead and the rim 30. The end 33 of the hookengages the shoulder 34 of the rim of the tire to hold the tire againstthe uprights 3 and 4. Downward force on the handle l2 will cause thelinks 16 and IT to push the bar 20 downwardly at an inward angle againstthe uprights so that the rounded ends 18 of the bar ride against saiduprights andthe upper end 35 of the arm will engage in the channel'between"the' uprights; thus exerting an outward force onthebar so thatits outer end 22 will tend to be inserted between the L furcated upperend, a. hook adjustably and pivotably attached-to one side of saidstandard for L l holding the tire against said standard, a lever bead 32of the tire and the rim an of the wheel to break the bond therebetvgeen.qAffiBljjh gbond has been broken, the links and arm may begp'nlledoutwardly and placed into a position such as c'a'ted'end of thestandard, links pivotally conshown in dotted lines in Fig. 1, sothatth'np'per' end 35 of the bar contacts the -lever arm L asindicatedat 36. Continued downward pressure on the bar in this position willfurther releasefithe tire from the rim. The tool may then be released atthis first' 'point of contact..and the .tire moved to a 'newpointof?cbntact-for2further breaking of the bond betwen the beadbm thetire and the rim of the wheel.

It will be obvious from the foregoing" that I have provided an-improved-toolforarernoving tires from the rims'of wheels and' whichwithlight force may be applied betweenthe"bead: on the tire and the rimtobreak thebdnd therebetween, and which tool is adjustable' to'flt allyattached to one =side*of said-standard for holding the tire againstsaidstandard; a lever pivotally connected insaid; bifurcatedend o'ffthestandard, links pivotally connectedto said; lever,

and an arm pivotally connected between the lower ends of said links, theinner lower edges of said links being slightly rounded for engaging theedges of the bifurcated standard to exert a downward and outward forceon the arm upon downward movement of the lever to press the lower end ofthe arm between the bead of the tire and r m 9 l ne .w
